iSACA Cybersecurity Fundamentals Certification Practice Exam

What is the function of Data Loss Prevention (DLP) systems?

1. To encrypt all data in transit

2. To prevent unauthorized sharing of sensitive data

3. To increase the speed of data processing

4. To manage user permissions on data access

The correct answer is: To prevent unauthorized sharing of sensitive data

Data Loss Prevention (DLP) systems are specifically designed to monitor, detect, and prevent unauthorized sharing or transmission of sensitive data. Their primary function is to safeguard confidential information from being leaked, whether intentionally or accidentally, by enforcing policies and controls over how and where sensitive data can be accessed and shared. DLP systems employ various techniques, such as content inspection and contextual analysis, to identify sensitive information and take protective measures, such as blocking data transfers, alerting administrators, or applying encryption. While encrypting data in transit is important for protecting data integrity and confidentiality, it is just one aspect of a broader security strategy and not the main function of DLP systems. Similarly, increasing the speed of data processing and managing user permissions are relevant to data security but do not encapsulate the primary purpose of DLP, which is focused on preventing unauthorized disclosures of sensitive data. Therefore, the correct answer highlights the core function of DLP systems in protecting sensitive information across different environments.
